Reviewed on December 10, 2007AMD's new Phenom quad-core CPU has little to recommend it over competing chips from Intel. The Phenom is marginally less expensive, but not enough to make up for its subpar performance. Unless AMD drops prices more aggressively, it looks like Intel will maintain its grasp on the CPU market for the foreseeable future.TAGS:Intel Core 2 Duo, AMD, quad-core, Intel, PC
Reviewed on November 1, 2006If you thought dual cores were over the top, get ready. Intel presents the Core 2 Extreme QX6700, a single CPU with four distinct processing cores. At $999, the first quad-core CPU will remain an enthusiast part for a while, but as a glimpse of the future, it's clear that clock speed is out and core counts are in.TAGS:Intel Core 2 Extreme, multi-core, quad-core, clock speed, digital media, dual-core, Intel Core 2 Duo, Intel, CPU, AMD, PC

Reviewed on October 28, 2007The CPU market is due for a lot of upheaval over the next 12 months, so you might be wise to wait for a clearer picture before plunking down $1,000 or so on Intel's new Core 2 Extreme QX9650 quad-core desktop processor. But if you want to claim ownership of the fastest multicore CPU around today, look no further.TAGS:Intel Core 2 Extreme, Intel Core 2 Duo, transistor, Intel, quad-core, digital media, CPU
Reviewed on July 17, 2007The quad-core Core 2 Extreme QX6850 keeps the desktop CPU performance belt tied firmly around Intel's waist at a price that helps offset the lack of sizable performance gains. New products at the end of the year may outclass this new chip when they arrive, but for now, the QX6850 reigns supreme.TAGS:Intel Core 2 Extreme, quad-core, clock speed, bus, Intel, Intel Core 2 Duo, motherboard, multimedia, AMD, CPU, chipset
Reviewed on March 26, 2008AMD's new Phenom X4 9850 is overpriced and outclassed compared with its Intel-based quad-core competition. If PC vendors can use this chip to make cheap systems (as they did with older Phenoms), we might have nicer things to say, but as a DIY part at this price, we can't recommend AMD's latest quad-core CPU.TAGS:HyperTransport, AMD, quad-core, Intel, Intel Core 2 Duo
